Airbag control unit with part number 98820-5RL0A

What does the airbag control unit 98820-5RL0A do?

The airbag control unit 98820-5RL0A controls the restraint system (SRS) in Nissan. It processes the measurements from the crash sensors and, in the event of an accident, decides which airbags and seatbelt pretensioners are triggered. It also monitors the system constantly and reports faults via the airbag warning light.

After an accident the unit stores crash data and locks itself. The protective effect of the system depends on this control unit working without faults.

Why does the control unit 98820-5RL0A fail?

The most common cause: stored crash data from an accident, even if no airbag was deployed. In the 98820-5RL0A it cannot be erased with a normal diagnostic tool. Other causes include aged components, cold solder joints, moisture and corrosion, and voltage spikes.

Airbag24 erases the crash data during the repair. An attempt to erase it yourself with a normal diagnostic tool does not work.

• Aged electronic components that gradually lose their function.
• Cold solder joints inside the unit.
• Moisture and corrosion at plug connections.
• Voltage spikes, for example from a weak battery or a jump start.

Which cause applies in an individual case is only shown by the examination of the unit.

How can you tell that the 98820-5RL0A is defective?

A defect in the 98820-5RL0A shows up as the airbag warning light in the instrument cluster, which lights up permanently or intermittently, and as fault messages in the instrument cluster.

• The airbag warning light lights up permanently or only intermittently.
• A fault message appears in the instrument cluster.
• The diagnostic tool cannot connect to the control unit.
• The fault memory cannot be erased.

In an emergency, airbags and seatbelt pretensioners may then fail to trigger. The warning light should therefore be taken seriously, even if it only lights up intermittently.
